SPECIFICATION forming part of Letters Patent No. 695,119, dated March11, 1902.

Application filed November 13, 1899. Serial No. 736,834. (No model.)

To all whom it may concern:

Be it known that I, VERNON R YLE, a citi zen of the United States, and aresident of Paterson, in the county of Passaic and State of New Jersey,have invented a new and useful Oylinder-Routing Machine, of which thefollowing is a specification.

My invention relates to a cylinder-routing machine in which the cylinderto be operated upon and the cutting-tool are arranged the one to movebodily toward and away from the other and the cutting-tool to follow aline corresponding to an element of surface of the cylinder and a linetransverse to the element of surface, the several movements of the tooland the cylinder to be routed being within convenient control of theoperator.

In the accompanying drawings, Figure 1 is a view of the machine in frontelevation, the position of the cylinder to be routed being indicated bya broken line. Fig. 2 is an end view of the same. Fig. 3 is a top planview. Fig. 4 is a view in detail showing the means for chucking thecylinder. Fig. 5 is an enlarged view in detail of the means for adjusting the cylinder-operating mechanism in different positions relative tothe operator. Fig. 6 is a vertical section of the same along the line 66 of Fig. 5. Fig. 7 is a top plan view of the parts represented in Fig.6. Fig. 8 is an enlarged View in detail, showing the drum for applyingtension to the wire which transmits a rotary motion to the cylinder.Fig. 9 is a top plan view of the drum, and Fig. 10 is a plan view of thelower section of the drum.

The machine illustrated in the accompanying drawings to show a practicalembodiment of my invention provides for mounting cylinders of varyi ugdiameters and varyinglengths, so that their upper element of surfacewill 00- cupy a predetermined position in space and so arranging thecutting-tool that it may be moved bodily toward and away from thecylinder at any point along its upper element of surface, while thecylinder itself may be rotated back and forth at will beneath the cutter to permit the latter to operate upon the cylinderat any point of theperiphery desired.

The column which forms the main support for the operating parts isdenoted by A and is extended laterally at its base a to form a stablesupport. The cylinder to be routed is supported, primarily, from thebase of the column A, and the cutting-tool, together with a slide andway for conducting the tool along the upper element of surface of thecylinder, are pivoted, primarily, to the top a of the column A, which inthe present instance is given a rearward and upwardslant from the bodyof the column, as clearly indicated in Fig. 2.

The support, vertical adjustment, and rotary adjustment of the cylinderare provided for as follows: A pair of hollow pedestals B B are fixed tothe front of the base a of the column and on these pedestals worm-wheelsO O 'are mounted, having fixed to rotate therewith nuts Z) Z). Theworm-wheels G O are rotated. by worms (not shown) on a shaft 0, mountedin suitable bearings fixed to the pedestals B B, the said shaft beingrotated by means of a crank-wheel c. A horizontal wayD is located abovethe pedestals B B and from it depend screws (1 d, which screws engagethe nuts I) b and pass through the worm-wheels G 0 into the hollowpedestals B B. It therefore follows that when the shaft 0 is rotated bythe crank-wheel c the wayD and the parts carried thereby will beelevated or lowered by the ac tion of the nuts Z; l) on the screws dd.The way D is guided and held steadily by means of rearwardly-extendingarms 61 which have a sliding connection at their ends with dependingrods a fixed to the column A. On the way D are mounted a head-block Eand a tail-block E. The blocks E E have a dovetailed engagement with theway D and are split, as shown at c, Fig. 2, and provided with athrough-bolt e for the purpose of locking them to the way D in anydesired adjustment. The blocks E E are connected by a shaft 6 rotatablymounted therein,and provided with chucks c e for holding the cylinder inposition on the shaft.

The arrangement for holding cylinders of varying lengths on the shaft eis as follows: The tail-chuck e is made bodily adjustable along theshaft 6 at frequent intervalsin the present instance by means of a pin 6which extends through the base of the chuck and through one of theopenings 6 in the shaft. This serves to locate the two chucks a distanceapart corresponding to the length of the cylinder to a degree equal toor less Ice than the distance between two consecutive holes 6 in theshaft, and the two chucks are then drawn into snug engagement with thecylinder-by means of a draw-bolt F, provided with an operating-wheelfiextending through a sleeve f, (see Fig. 4,) in which the headchuck eis held, and into screw-threaded engagement with a socket e in the endof the shaft 6 By turning the draw-bolt F the shaft e with thetail-chuck e fixed thereon, will be moved longitudinally,carrying thechuck 6 toward or away from the chuck e to clamp or release thecylinder, as may be required. The cylinder, no matter what its diameterand length, may thus be clamped in position between the head and tailblocks E E, and by raising and lowering the way D the upper element ofsurface of the cylinder may be brought into a predetermined position inspace ready for operation. When so adjusted, the cylinder may berotated, together with the shaft 6 as follows: The sleeve f, whichcarries the draw-boltF and chuck e ,is mounted in suitable hearings inthe head-block E, and the wheel G, for operating the shaft 6 and thecylinder thereon, is fixed to the sleeve f, as clearly shown in Fig. 4.A wire g, through which power is transmitted to the wheel G, afterpassing one or more times around the wheel G extends downwardly uponopposite sides of the head-block E, thence under guide-pulleys g 9 theone at the front and the other at the rear of the way D, the one partextending along the rear of the way D to the upper section H of thetension-drum, to which it is secured after passing one or more timesaround the drum-section, and-the other part extending along the front ofthe way D to and one or more times around the operating-wheel I, andthence to the lower drum-section H, to which, after passing one or moretimes around its periphery, it is secured.

The wire 9 is held constantly under the desired tension by the drumcomposed of the sections H H, to the former of which, as hereinabovestated, the part of the wire to the rear of the way is attached and tothe latter of which the part of the wire at the front of the way isattached. These two sections H H of the drum are mounted to rotatehorizontally relatively to each other, the lower section H being in thepresent instance fastened to an upright shaft h and having the uppersection H loosely mounted on the hub of the lower section H. The lowersection H has fixed to its upper side a ring 71, having gear-teeth onits periphery, and these teeth on the ring it are engaged by a pinion77. fixed on a short rock-shaft k extending upwardly through a bearingin the upper drumsection H and having fixed to its upper end a lever-armh, the free end of which is attached by a spring h with a stud 71 set inthe top of the section H. It thus follows that the sections H and H ofthe drum are connected by means of the pinion k and gearing It, so that,assuming the upper section H to be for the moment stationary, thetension of the spring h, tending to draw the end of the lever k towardthe stud h will tend to rotate the lower section H of the drum in thedirection to wind the wire 9 at the front of the way on the drum, andhence hold it taut. On the other hand, assuming the lower section H tobe stationary, the spring 71 will tend to rotate the pinion k and henceto cause it and the drum-section H, which carries it, to travelrelatively to the lower section in a direction to wind the part of thewire at the rear of the way on the said upper section H, and hence holdit taut. In practice the one or the other of the sections H H will giveway as the tension becomes too great onit until it is balanced by thetension upon the companion section, so that the two parts will be at alltimes under equal tension, which is to be primarily determined by thestrength of the spring 72 I further provide for the slight raising andlowering of the drum H H as it winds and unwinds the wire to prevent thelayers of wire from overlapping one another. This is accomplished asfollows: The shaft h has in its upper end an interiorly-screw-threadedsocket h which engages a fixed screw h set in the top of the way D andfixed against a rotary movement. The pitch of the screw it is such thatas the drum-sections H H rotate and carry with them the shaft h it will,by its screw-threaded engagement with the screw 71. gradually raise andlower to accommodate the position of the wire thereon.

The wire-operating wheel I has fixed to its front a ring 7;, provided onits periphery with gear-teeth which engage a pinion t" on a shaft '6which extends forwardly and carries on its front end a star-wheel i Itis desirable that the star-wheel 6 some one of the arms of which aregrasped by the operator to operate the wire g, and hence rotate thecylinder, should be within convenient reach of the operator at allpoints throughout the length of the cylinder wherever the cutter may beat work, and to this end I have provided means for raising and loweringthe star-wheel and also for moving it bodily along the way D withoutdisturbing the engagement of the wheel I with the wire. In the presentinstance the star-wheel is provided with four arms; but it may beprovided with agreater or lesser number of arms, as may be founddesirable. It and its shaft carrying the pinion 2" are mounted in abracket i fixed to or formed integral with a housing t arranged toprotect the gearing and provided with a hub i which forms a bearing forthe wireoperating wheel I and which in turn is mounted on a hollow axle1J fixed in the depending front portion of aslide K, fitted to the wayD. The axle i is conveniently screwed into the depending front it of theslide and carries a head i at its front end, which serves to hold thehub 11 tightly against the front is of the IIO slide in whateverposition the star-wheel may be adjusted in its r'ot'aryadjustment'around the Wheel I. For example, if the star-wheel, when thepinion t" is at the top of the toothed ring 't, be too high the axle 17may be loosened by applying a wrench to its headt' and the housing ttogether with its bracket carrying the star-wheeland its pinion t", maybe rocked on the axle 11 either to the left or right, the pinion t"working idly in the teeth in the ring 2' until the star-wheel hasreached the position desired, and in that position it may be firmlylocked by screwing the axle i into the front of the slide, so'as tocramp the hub i firmly between the head i of the axle and the front faceof the part 76. In addition to this bodily upward and downwardadjustment of the star-wheel it and the parts con-' nected with theslide K may be bodily adjusted along the way D and locked in position bymeans of one or more vertically-movable locking-pins--in the presentinstance two, denoted by L and IJ-arranged to move vertically in socketsformed in the depending portion 3 of the slide, as shown in Figs. 5,6,and

7, and having their upper ends wedge-shaped, so that when they areforced upwardly they will wedge between the front of the way D and therear of the depending portion it of the slide, and hence lockthe slidein position, and when allowed to drop will release the slide K andpermit it and the parts carried thereby to be moved along the way D.Power is applied to and removed from the pins L L by means of anangle-dog mounted on a pin Z, held between a pair of lugs 7: 7,0 on thedepending port-ion 7c of the slide. The angle-dog is provided with anupright arm Z and with a pair of short forwardly-extending arms,(denoted by Z the position of which are shown in Fig. 6, and one ofwhich, Z is shown in full lines in Fig. 5. The arms Z" extendunder theends of the pins L L in position to drive the pins upwardly or allowthem to drop as the dog is rocked on its support and the upright arm Zof the dog is in position to be engaged by a longitudinally-sliding pinZ resting in the bore of the hollow axle t and adapted to be driven intoengagement with the arm Z of the dog or released therefrom by aset-screw P, which extends through thehead of the axle and has ascrew-threaded engagement with the interior of the axle. From this itfollows that when it is desired to move the star-wheel bodily alongtheway D to suit the position of the cutter for the time being the screwZ may be turned to release the pin Z from the angledog, which in turnwill release the lockingpins L L and permit the slide-K to be movedalong the way D at pleasure, the wheel I accommodating itself to its newposition by idly rotating under the friction of the wire around it. Whenthe slide K has reached the position desired it may be locked in amoments time by simply turning the screw Z into engagement with the pinl", which by its engagement with the angle-dog willforce thelocking-pins L L and cramp the slide K securely in its place, so thatwhen the wheel Z is turned by means of the star-wheel motion will becommunicated through the wire to the shaft which carries the cylinderand it will be rocked the one way or the other according as thestar-wheel is turned in one way or the other to bring the cylinder inthe desired position with relation to the cutter.

The means for moving the cutter toward and away from the cylinder andalong the upper element of surface of the cylinder while it is beingdriven at a high rate of speed are as follows: A horizontal way M issupported on a pair of forwardly-extending arms in m, which arms arepivotally secured to the top a of the column A. In the present instancethe top Ct of the column is composed of a pair of upwardly andrearwardly extending arms provided at their upper end with bearings fora rockshaft m to which the arms on m are fixed, so as to rock togetherwith the shaft m in the bearings in the top of the column. The way Mextends horizontally along in proximity to the position which the top ofthe cylinder to be operated upon is to occupyviz., parallel with anelement of surface on the cylinder-and supports a carriage N, whichcarries the cutter, and also means for driving the carriage back andforth along the way M. The carriage N is secured to the way M by meansof yielding gibs 7%, (see Fig. 2,) which serve to automatically take upwear. The yielding feature may be obtained by insertinga spring-washer nbeneath the nut n which holds the gib in place.

The mechanism for driving the carriage N along the way M is quitesimilar in its general character to that already described for rotatingthe cylinder. It consists of a starwheel 0, in the present instanceprovided with six arms orhandles and carrying a pinion 0, (see Fig. 2,)in mesh with a gear-wheel 0, fixed to rotate with a wire-receiving drum0 the drum, the gearing, and the star-wheel being all supported in asuitable manner on the top of the carriage N, and the shaft sup portingthe star-wheel and its pinion 0 being mounted in suitable bearings in ahousing 0 arranged to be adjusted around the gearwheel on the drum 0 tobring the star-wheel nearer to or farther away from the operator in amanner quite similar to that hereinbefore described for bringing thestar-wheel i into a higher or lower adjustment. The wire which engagesthe drum 0 is denoted by P and is fixed at one end to a postp on the wayM and at its opposite end is attached to an arm 19, fulcrumed on anadjustable pinp and having its free end connected by a spring 19 with afixed support 19 The wire is conwill carry the cutter bodily by means ofthe adjusting-pin 19 to which the arm 10' is fulcrumed and which has ascrewthreaded engagement with its support 19 In the present instance thedrum 0 attached to the carriage, is carried bodily along the way M withthe carriage as it is rotated, taking up and paying out the wire, whichhas a frictional engagement with it, and this motion along parallel withthe way M.

The cutter,which maybe of any well-known or approved form, is denoted byQ and may be fixed to its spindle in any well-known or approved manner,the spindle itself being mounted in a support q, having a verticaladjustment on the face of a forward projection n on the carriage N. Inthe present in stance the cutter-spindle support has a dove tailedengagement with the front of the part 17., so that cutters of varyinglengths may be employed as occasion may require.

To further accommodate the cutter-support q to the rising-and-fallingmovement which is imparted to it as the carriage and its way are raisedand lowered, I provide a jointed and longitudinally-extensible rod g,which extends between the cutter-support q and the spindle 1 on whichthe intermediate drive-pulley R is fixed. A belt 1" leads from theintermediate drive-pulley R to a pulley R on the cutter-spindle, and abelt 7" leads from a drive-pulley R on the drive-shaft to a pulley R onthe spindle (1 which carries the intermediate pulley R. The spindle g issupported in the end of an arm 5, projecting from a bracket S at the topof the column A,and the spindle qiwhich the drive-pulley R is mountedon, is supported in the bracket S and is provided with fast and loosepulleys 3' 8 which are actuated by means of a belt s leading to a sourceof power. (Not shown.) A belt-shifter of any well-known or approved 7form operated by a lever-s serves to start and stop the action of thecutter at pleasure. It will thus be seen that the cutter-support g,while its position is determined by the carriage N along a predeterminedline, which in" the present instance is parallel with an element ofsurface of the cylinder, is con nected with its driving mechanism by ajointed arm, which at the spindle g as its joint permits a folding andunfolding of the arm in a horizontal direction, while the jointed rod qpermits the slight rise and fall of the whole by t) and which issupported by the pedestals B B and which may be of any wellknown orapproved form. The downward movement of the arms m m and the partscarried thereby is determined by means of a pair of adj usting-screws,(indicated in dot ted lines in Fig. 3 and one of them shown in fulllines in Fig. 2, denoted, respectively, by u u.) 'By this means thedepth of cut of the tool may be accurately determined, and the operatorhas only to pay attention to the lifting of the tool out of engagementwith the work, so far as the upward and downward movements of the cutterare concerned.

The operation of the machine as a whole may be briefly stated asfollows:The cylinder having been placed in position so as to bring itsupper.surface in proper relation to the cutter and the cutter havingbeen set in motion, the operator, with one hand on the star-wheel ianother on the star-wheel O, and his foot on the treadle t, controls themovement of the cylinder to bring the cutter into engagement with itssurface at the proper point laterally of its length, while with the star-wheel 0 he moves the carriage, and hence thecutter, longitudinallyalong the cylinder to bring the cutter into engagement with the cylinderat the proper position lengthwise of the cylinder, and with his footlifts the cutter out of and allows it to drop into action at pleasure.The operator thus has under his perfect control by the several adjustments within his convenient reach means for promptly and accuratelybringing the cutting-tool into engagement with the cylinder at any pointhe pleases throughout the surface of the cylinder, and in addition tothis he may operate upon cylinders of varying diameters and lengths asoccasion may require.

It is obvious that changes might be resorted to in the form andarrangement of the parts without departing from the spirit and scope ofmy invention. Hence I do not wish to limit myself strictly to thestructure herein shown and described; bu
